UPDATED Nov 19, 2004 The Unmanned Aerial Vehicle (UAV), is a term you'll hear a lot more about over the coming years. In the past it has mainly been mentioned whenever a technologically advanced country (aka the USA) is involved in warfare. The biggest advantage of a UAV is that it can be put 'in harm's way' - it can be put in a dangerous situation where the odds of losing a pilot (the most valuable part of any aircraft) are simply too great. Now Yamaha has unveiled a range of Unmanned Ground, Marine and Air Vehicles that bring autonomous capability to the world around us.
